' LOOSE-LEAF BINDER.

Specification of Letters Patent. Patented Apr, 21 1914 Application filedDecember 28, 1912. Serial No. 739,009.

To all whom it may concern Be it known that we, ROBERT REIFEL, a citizenof the United States, and Gnoncn BLA'rTEL, a subject of the Czar ofRussia, and residents of New York,in the countyof New York and State ofNew York, have 1nvented certain new and useful Improvements inLoose-Leaf Binders, of which the following is a specification.

This invention relates to loose leaf binders and has for its object asimple and quickly operated means whereby the leaves may be inserted orremoved and the cover of the binder thrown back, regardless of thethickness of the book, for making records or reference, as will be morefully described in the following specification, set forth in the claimsand illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view of a loose leaf binder comprising thisinvention and with the back thrown open. Fig. 2 is a side view of thedevice. Fig. 3 is a view of the essential parts of the invention fromthe rear. Fig. 4: is a detail view of one of the links. Fig. 5 is a planview of the binder partly broken away. Figs. 6 and 7 are detail views.

In a loose leaf binder instant release or insertion of the sheets isvery necessary and the means for accomplishing these objects must besimple, accessible and readily operated, and in providing these featuresthis device comprises the base board 10 having inclosed at one end ametal plate 11 with four or more studs 12 arising from its upper side.The studs 12 are threaded to screw into the lower ends of tuhular'postsl3 and 14, the latter being tapered at their upper ends for theconvenient passage of the perforations of the leaves 15 as they aresecured in the binder. I

The posts 13 are, provided on their rear sides with longitudinal slots16 and lateral slots or branches 17 and may be tapered if desired. Theposts are located as at the corners of a rectangle and act in pairs,each of the posts 13 cooperating with the post 14 at its end of therectangle to receive a link 18 of steel wire which is arched at the topand whose ends are adapted to fit in the adjacent tubes. One end of thelinkis longer than the other and is adapted to be carried in the post 13while at the lower end of this longer end is swiveled a knob tubes.

19 whose "stem 20 slides in the slot 16 and i may be diverted into oneof the lateral slots 17.

The knob 19 and its stem are capable of locking the link at any desiredheight in the tubes so as to retain the sheets in the binder and toprovide for a pile of sheets of different thicknesses. In order to placeadditionalsheets on the 19 is thrown around and alincd with the slot 16when the link is raised until its short end clears the upper end of thetube 14. The link is then swung around tothe position shown at the rightof Fig. 8 and may be retained at that position by rotating the knob intothe uppr lateral slot. Both links are thus swung around and the cover orback board 21 removed, aifording access to the sheets or permitting newsheets to be placed on the posts. On replacing the cover the links areswung around, the knobs released and both ends of the links drop intothe by throwing the knobs around and into-the lateral slots. The tubesand links would ordinarily prevent the opening of the back 21 to aposition where it' would remain and to provide means to permit itsremaining open the back is made with slots 22 to receive the links andallow the cover to be thrown back 1nto a position where it will remain.

The back board andsheets are provided with the usual perforations to fitover the posts and those in the back board and its slots 22 may be linedwith metal. It is obv1ous that the parts may be modified or otherwisearranged without departing from the essential features above described.

In the upper end of the short arm of the link 18 is a reduced portion 23while the perforations 24 of the leaves 15 have a lateral slot or outlet25 to the rear edge of the sheet. It is oftennecessary to shift the topsheet of the leaves to one side to compare the final col..mns of thesheets. The sheet is then lifted, after the cover 21. is swung over,until the outlet 25 reaches the reduced part 23 where it is extractedand replaced by means of the adjacent outlet into the position showninFig. 5 where it will be seen that the edge 26 of the lower sheet isexposed for comparison with the upper sheet. The sheets may be thusremoved without destroying the perforations or injuring the outlets andthe sheets are held firmly in place but upon re-' posts 14, the knob Thelinks are then locked in place ends adapted to fit in moving orreplacing the entire assemblage of leaves the links are disconnected asabove described. 7

What we claim as new' and desire to secure by Letters Patent is:

1. In loose leaf binders, the combination with a base, of tubular posts,a link with the posts, and a swiveled stud on' one end of the link andadapted to be locked in one of the posts. I

- 2. In a loose leaf binder, the combination with a base, of tubularposts in pairs, one post of each pair being slotted, removable linksentering and connecting the posts, and

vmeans on one end of each link and operating in the slots of a post toadjust and lock the lin r.

3. In loose leafbinders, the combination with a base, of tubular posts,a link with ends adapted to fit in the posts, locking means at one endof the link, and means on the tube cooperating therewith to permit thelinks to be locked at different heights.

4:. In loose leaf binders, the combination with a base, of tubular poststo receive the leaves, cooperating-slotted posts, links having ends tofit in the posts, and swiveled studs at one end of the links to work inthe slots and be locked at a desired point.

5. In loose leaf binders, the combination with a base, of a platetherein, tubular posts secured to the plate, those at one side havinglongitudinal and lateral slots, links with ends of different lengths,swiveled studs and knobs on the longer ends of the links and adapted toplay in the slots to lock the links at certain points, and a cover withslots to pass over the links and posts.

6. In loose leaf hinders, the combination with a base, of tubular postswith slots secured to a plate in the base,leaves with perforations andoutlets, links with ends of dif ferent lengths and reduced in thicknessat the shorter end, locking means at the longer end of the link andoperating in the slots of the posts, cooperating posts for the shorterends of the links, and a cover hinged on the cooperating posts andhaving slots to enable it to pass the links.

Signed at New York in the county of New York and State of New York this27 day of December A. D. 1912.
